Application led June 27,' 1905. Serial No. 267,246.

WEILER, a citizen of the UnitedStates, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvement in Butter-Pat-- Printing Machines, of which the following is a specification.

This invention relates to an improved machine for printing or molding pats 'of butter for its object to prints.

With these briefly-stated objects in view the invention comprises certain details of construction and peculiar combination and arrangement of parts', as will be fully set forth 1n the following specification and pointed out in the claims, reference being had to the drawings, in which`v Figure 1 is a perspective viewrof my improvement as in use. Fig. 2 is a vertical longitudinal sectional view 'of the same. Fig. 3 is a sectional view drawn on the line Fig. 2 and looking in the direction indicated by the arrow. Fig. 4 is a detail sectional view drawn on theline 4 4 of Fig. 3. is a detail view showing an addition which may be embodied in the invention, and Fig. 6 is a detail section drawn through the cylindrical portion of the casing.

In carrying out my invention I employ a A,- which comprises a cylindrical section A and a trough-section A2,v the whole being supported by suitable legs A3, having foot portions by which the device may be securely positioned u upon the section A on a .table or other support, One end A o the casing is semicylindrical in cross-section and hasa semicircularshape top B hinged thereto, which when folded over forms a complete cylinder, and this section B is provided with a hopper B, through which the material is fed into the cylinder.

' When the sections are foldedvto form the cylinder, they are held together at their outer ends by means of a cap B2,'which closes the end of the cylinder and also forms a bearing y of a conveyer or feed-screwfor the shaft C n C, and to the outer end ofthe shaft C" is held a crank-lever C2, by which theconv'eyer is operated.

At the opposite end of the semicylindrical section A the casing terminates in a semicircular trough-shape section A2, whose sides Fig. 5

. tions downinto the trough extend vertically and in parallel relation, one

side of which has va lateral extension D, providing a hopper D for the reception of ice, and thelower portion of the side adjacent and at the base of the hopperis perforated, as shown at'D2, through which the water from the melted ice may escapeand flow into the trough'for the purpose as will be eX- plained later on. v

The opposite side of the trough is provided with a vcentral vertical extension D3, from the inner side' of-which extends a stub bolt or shaft D4, and upon the bolt or shaft is loosely mounted a mold-wheel E, said wheel comprising a hub E, a side E2, and the rim or periphery E3, the latter containing a seriesof depressions forming molds E4, which may be of any suitable shape `or design, and operating in the molds are plungers F, carried by rods F, whose inner ends work through guidelugs E5, formedupon the inner surface of the side of the wheel. The eXtreme inner ends of the rods are bifurcated and have y antifriction-rollers `F2 journaled therein, that work around an eccentric cam F3, upon the outer end of the shaft to normally hold the plunger in the inner ends of the molds, I employ springs F4, which surround the` rods andbear between the inner D4. 4In order surface of the'rim and collars held upon the g rods.

In order tol revolve the wheel to bring'the mold opposite the inner end of the cylinder, I arrange a gear vGr upon the shaft C, which bears `against .the head 1B is meshed by a pinion G,

carried by a shaft G2, vjournaled upon the'side of the casing, and

vuponthe opposite end of thisshaft is a pinion G3, which meshes a circular rack-section G4, formed upon thev outer side of the wheel E, and it will be readily understood that when A'the crank-handle C2 is turned motion will'be simultaneously imparted to the conveyer to feed'the material ytoward the open end of the hopper and tothe mold-wheel to bring the molds opposite the said open end of the cylinder, and in practicel I propose to converge the open end of the cylinder to a size substantially that ofthe diameter of the molds.

' The operation of myinvention is as follows: l

Ice is iirst put intothe hopper D', from which the drippings willflow through' thev perforav A3, formed in the casing, and the materialto'be molded is then placed the hopper. The crank-handle is then revolved, Whichforcibly'feeds the mateof the cylinderfand securely held IOO rial through the cylinder and into contact with the periphery of the mold-wheel, and as the molds are brought opposite the cylinder the material will be forced therein, where it will remain until that portion of the periphery of the wheel is revolved to the opposite side or the end of the casing, and during this movement the rollers carried by the plungerrods will engage the eccentric portion of the cam and force the pistons outwardly, and likewise the pat of butter that has been formed, and as the wheel continues to revolve the pat of butter will strike against the end of the casing and drop off into a suitable pan er receptacle that has been placed adj acent the machine. As the wheel continues to revolve the molds are first passed through the water held in the trough, which completely saturates and prevents the butter adhering thereto or to the periphery of the wheel or plunger, and it will thus be seen that I provide an exceedingly efiicient device by which a quantity of pats or molds of butter may be made in a very short space of time and which will be found of great convenience to proprietors of hotels, cafs, and such places, and much time will be saved over the slow tedious process of molding the pats by hand, as is new done.

In Fig. 5I show a paddle-wheel for delivering the pats of butter as they are projected from the molds and which I may find it desirable to use in connection with my machine, and by reference to the said ligure it will be seen I provide the casing with rearwardly-extending ears K, in which is journaled a shaft L, having a paddle-blade L fastened thereon, and upon one end of the shaft L is mounted a beveled pinion L2, which meshes a similar pinion M, secured upon an extension M of the shaft G2. By this arrangement it will be understood that as the wheel is revolved and the pat of butter reaches its extreme outermost position in the mold the paddle-plate will be revolved in a direction opposite that in which the mold-wheel is revolving and coming in contact with the pat of butter will remove the same from the plunger and deliver it into any suitable receptacle placed adjacent the machine.

In practice I may connect the lower ends of the legs A3 and provide the connectingstrip with a lateral U-shape extension having a clamping-screw, by which the machine may be securely clamped upon the edge of a table or bench, as shown in dotted lines in Fig. l of the drawings, and, further, I may provide the semicircular portions of the casing with laterally-extending bifurcated lugs a and 6 adapted to receive clamping-bolts, by which the sections may be securely held together, and when these lugs are provided I propose to dispense with the cellar B2 and form the outer ends of each sefnicylindrical section with an end portion that is cast integral with each section, and in this case the abutting edges will be recessed to provide a bearing for the shaft of the screw.

It may be stated that in practice I also propose to make the face of the plungers with a suitable design, such as a clever, strawberry, or, in fact, any design that may be found to ones taste.

Of course it will be understood that as the plungers have been pushed te the ends of the molds by the cam and the wheel continues to revolve the springs surrounding the plungerrods will force them inwardly to the betteln of the molds.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A butter-printing machine comprising a horizontally-arranged cylinder, a feed-screw arranged in said cylinder, a hopper carried by one end of the cylinder, a trough adapted to contain a liquid carried by the opposite end of the cylinder, a rotatable mold-wheel journaled in the sides of said trough and extending into the liquid and forming an end for the cylinder, and means for rotating the feedserew and the mold-wheel simultanemisly.
